A Connection Between The Perturbative QCD Potential and Phenomenological Potentials
Y. Sumino
Abstract
When the cancellation of the leading renormalon contributions is incorporated, the total energy of a b bbar system, Etot,bbbar(r) = 2 mpole,b + VQCD(r), agrees well with the potentials used in phenomenological models for heavy quarkonia in the range 0.5 GeV-1 < r < 3 GeV-1. We provide a connection between the conventional potential-model approaches to the quarkonium spectroscopy and the recent computation based on perturbative QCD.
